Owner's Manual blood pressure monitor

Introduction

Congratulations on the purchase of your Monitor 3 Air dive

computer. Our designers have condensed important dive

planning information into a user-friendly dive instrument.

By combining graphics with bold alphanumerics, we have

created an easy-to-use computer that provides dive data at

a glance.

As with all diving equipment, it is important to understand

the features and functions of the Monitor 3 Air. Before

using the Monitor 3 Air, it is essential to read this manual

in its entirety. Contained within this easy to read manual

are illustrations to aid you in the complete understanding

of the computer.

Section 1 instructs you on preparing the Monitor 3 for its

first use. Section 2 explains all the functions and screen

displays while on a dive. Section 3 shows you how to recall

the dive memory. Instructions on planning a future dive are

given in Section 4. Care & Maintenance tips are covered in

Section 5. Lastly, the reference section contains the

technical specifications and a description of the algorithm.

What is a “Dive Computer”

DEFINITION OF COMPARTMENTS

A dive computer is an instrument that mathematically

simulates the absorption and release of nitrogen by

hypothetical tissue types in the human body. These

hypothetical tissues are commonly referred to as “compart-

ments.” Each compartment absorbs and releases nitrogen

at different rates. The Monitor 3 Air tracks these compart-

ments constantly, providing you with up-to-the-minute

decompression information.

MULTI-LEVEL DIVING

If you use, or have used, dive tables you know the total

amount of time you can stay under water is based on the

maximum depth reached during the dive. Dive tables, such

as the U.S. Navy dive tables, assume that you immediately

descend to a single depth, stay at that depth for the

duration of the dive, then immediately surface from that

depth. This type of dive profile is referred to as a rectangu-

lar dive profile (figure 1). In reality, however, most recre-

ational divers go to the deepest depth first and make a

gradual ascent to the surface. This type of dive profile is

referred to as a multilevel dive profile (figure 2).
